The Campagnolo 03 AFS Disc Rotor is a high-performance components engineered to handle the extreme thermal loads of long mountain descents. By combining a tempered stainless steel braking surface with a lightweight aluminum spider, this rotor provides a high level of safety and consistent stopping power in both wet and dry conditions.

• Advanced Heat Management: The two-piece floating design features an inner aluminum spider that rapidly dissipates heat away from the braking track. This design prevents the hub from overheating and ensures the rotor remains straight and true even under sustained, heavy braking.

• Safety-First Engineering: Designed with safely rounded outer edges, this rotor minimizes the risk of injury during handling and facilitates faster, easier wheel changes. To further reduce thermal stress, the rivets connecting the steel and aluminum sections are positioned away from the caliper, protecting delicate system components.

• Universal Standard Compatibility: While utilizing Campagnolo’s AFS (Axial Fixing System) designation, this rotor is fully compatible with the industry-standard Center Lock interface. It is optimized for use across Record, Chorus, and Ekar groupsets and works effectively with all brake pad compounds.

• Optimized for Performance: This 140mm version is a lightweight choice (approx. 99g) ideal for rear-wheel applications or for lighter riders seeking a balance of aerodynamic efficiency and sufficient stopping power.
